Current Yield of a Bond: The Quick Income Check, and What It Leaves Out

The current yield of a bond is the fastest income check in fixed income: take the coupon you get in a year and divide it by the price you pay today. Two numbers, one division, and you know roughly what the bond pays you on your money right now. That speed is exactly why people misuse it. We see bond listings, debenture offers and broker messages quote it as if it were the full return, and it isn’t. This guide walks through the maths, a few worked examples in rupees, and the specific blind spots you need to keep in mind.

What the current yield of a bond actually measures

The Reserve Bank of India’s primer on the Government Securities market defines current yield as the coupon payment expressed as a percentage of the bond’s purchase price. In plain words, it tells you the return you get against what you actually paid, which can be more or less than the face value printed on the bond.

The formula is short:

Current yield = (Annual coupon / Current price) x 100

Compare that with the coupon yield, which the same RBI primer describes as the coupon as a percentage of face value. The coupon yield is fixed the day the bond is issued. The current yield moves every time the price moves. That single difference is the whole reason the measure exists.

You will also hear it called running yield, flat yield or income yield. Wikipedia’s entry on current yield lists these names, and they all mean the same ratio of annual interest to price.

The RBI’s own worked example

The RBI primer uses a 10-year bond with an 8.24% coupon and ₹100 face value, trading at ₹103. The annual coupon is 8.24% of ₹100, which is ₹8.24. Divide that by the ₹103 price and you get a current yield of 8.00%.

Notice what happened. The bond’s coupon is 8.24%, but because you paid a ₹3 premium over face value, the income on your money drops to 8%. Nobody changed the coupon. You simply paid more for the same stream of interest.

The coupon never changes after issue. Your price does. Current yield is just the coupon re-expressed against what you actually paid.

Three quick examples in rupees

All three below are hypothetical bonds, built only to show the arithmetic.

1. A corporate bond bought at a discount

Say a bond has a ₹1,000 face value and a 7.5% coupon. It pays ₹75 a year. If it trades at ₹950, the current yield is 75 / 950, or about 7.89%. You collect the same ₹75 as someone who bought at par, but on a smaller outlay.

2. The same bond at a premium

Now the same bond trades at ₹1,050. The ₹75 coupon divided by ₹1,050 gives roughly 7.14%. Same paper, same issuer, same interest cheque, and the income yield is lower by about three-quarters of a percentage point purely because of the price.

3. A G-Sec that pays twice a year

Dated government securities in India pay their coupon on a half-yearly basis, according to the RBI primer. Take a hypothetical 7.20% G-Sec with ₹100 face value. It pays ₹3.60 every six months, ₹7.20 a year. If you buy it at ₹98, the current yield is 7.20 / 98, which works out to about 7.35%.

Here’s a small trap. You use the full annual coupon in the numerator, not the half-yearly payment. People sometimes divide ₹3.60 by ₹98 and conclude the bond yields 3.67%. That number is a six-month figure, not an annual one.

Discount, premium and par: how current yield sits next to the others

There are three common yield measures for a bond: coupon yield, current yield and yield to maturity. Wikipedia sets out how they line up for a coupon-paying bond:

• At a discount (price below face value): YTM is higher than current yield, which is higher than coupon yield.
• At a premium (price above face value): coupon yield is higher than current yield, which is higher than YTM.
• At par: all three are equal.

Our first example fits the discount pattern. The 7.5% coupon bond at ₹950 shows a current yield of about 7.89%, and its YTM would be higher still, because you also pocket the ₹50 gap when the bond is redeemed at ₹1,000. The premium bond works the other way. Its 7.14% current yield flatters it, because the ₹50 you overpaid disappears by maturity.

If you want the full picture on that redemption effect, our guide to yield to maturity covers how the measure folds in every cash flow until the bond matures.

What current yield leaves out

The RBI primer is blunt about this: current yield considers only the coupon interest and ignores the other sources of return. The same document lists those sources. A bond investor earns from the coupon payments, from any capital gain or loss when the bond is sold or matures, and from reinvesting the interest received along the way. Current yield sees only the first.

Wikipedia adds a few more gaps. Current yield is a snapshot at one moment. It says nothing about how long the bond has left to run, nothing about reinvestment risk, and nothing about price swings before maturity.

Let’s put that in a two-bond comparison. Both are hypothetical, both have ₹100 face value and three years left, and both pay annual coupons.

• Bond A: 9% coupon, priced at ₹108. Current yield is 9 / 108, about 8.33%.
• Bond B: 6% coupon, priced at ₹94. Current yield is 6 / 94, about 6.38%.

On current yield alone, Bond A wins by almost two percentage points. Now hold both to maturity and add up the rupees, ignoring tax and any interest earned on reinvested coupons.

• Bond A pays ₹27 in coupons over three years and returns ₹100 at maturity. You put in ₹108, so your net gain is ₹19, or about 17.6% of what you paid.
• Bond B pays ₹18 in coupons and returns ₹100. You put in ₹94, so your net gain is ₹24, about 25.5% of what you paid.

The bond with the lower current yield made more money. The premium on Bond A quietly ate into its return, and the discount on Bond B added to it. This is the single most common mistake we see with the measure, and it costs real money when people chase the highest number on a list of listed bonds or NCDs.

A high current yield on a premium bond can hide a capital loss that shows up only at redemption.

Why current yield rises when bond prices fall

The RBI primer states that the yield of a bond is inversely related to its price. With current yield the link is easy to see, because price sits in the denominator. The coupon is fixed, so when the price drops, the same rupee coupon is a bigger slice of a smaller number.

That’s why bond prices and yields move in opposite directions in the news. When markets expect rates to go up, existing bonds with lower fixed coupons become less attractive, their prices fall, and their yields rise until they line up with what new money can earn. Our explainer on gilt funds in India shows how that same price swing flows straight into gilt fund NAVs.

Clean price, dirty price and accrued interest

One more detail that trips people up. Bonds in the secondary market usually quote a clean price, which excludes interest that has built up since the last coupon date. The RBI primer explains that the total amount you pay on a trade includes this accrued interest on top of the price. The Wikipedia example also uses the clean price in its current yield calculation.

So when you work out current yield, use the quoted clean price, not the total settlement amount on your contract note. If you divide by the bigger, interest-inclusive figure, your yield will look a little lower than it really is, and the gap depends on how far you are from the last coupon date.

Where the measure still earns its place

None of this makes current yield useless. It does one job well. If you care about income, it tells you how much cash the bond will hand you each year relative to what you’re paying today. Retirees comparing a few PSU bonds for monthly or yearly income, or anyone matching coupon cash to expenses, will find it a handy first filter.

It is also a quick sanity check on a quote. If a broker shows you a bond with a 7% coupon and a stated yield of 11%, the current yield tells you whether that 11% could come from the coupon at today’s price. If the price is near par and the current yield is close to 7%, the rest of that 11% must come from somewhere else, usually a deep discount, a short time to maturity, or a credit risk the market is pricing in.

For callable bonds the gap gets even wider, because the issuer can redeem early. Our piece on yield to call walks through why a callable bond’s real return can sit below both its current yield and its YTM.

A simple checklist before you buy

1. Work out the current yield yourself from the annual coupon and the clean price. Don’t rely on a figure someone else quoted.
2. Check whether the price is above or below face value. A premium means the current yield overstates your return to maturity. A discount means it understates it.
3. Look at the years left to maturity. The shorter the time left, the more a premium or discount matters on a per-year basis.
4. Ask for the YTM, and for callable bonds, the yield to call. Compare those, not current yields, across bonds.
5. Remember that current yield says nothing about credit risk. A very high number on a corporate bond can be the market’s warning, not a gift. Our risk management guide covers how to size positions so one bad issuer can’t sink a portfolio.

The short version

Current yield is annual coupon over today’s price. It moves opposite to the price, it equals the coupon only when you buy at par, and it ignores the gain or loss you lock in by paying less or more than face value. Use it to judge income. Use yield to maturity to judge return. Mixing the two up is how a 9% coupon bond ends up earning less than a 6% one.
